Welsh Open: Ronnie O'Sullivan knocked out by Matthew Stevens
Five-time world champion Ronnie O'Sullivan is knocked out of the Welsh Open 4-3 in the third round of the Welsh Open by Matthew Stevens.
The world number two missed an adventurous red in the decisive frame and his opponent cleared up to win the match.
Stevens had not beaten O'Sullivan - who had criticised the venue earlier this week - in 12 years before the victory in Cardiff.
